Professor Moore’s times

The professor swims. Here are Professor Moore’s times (in minutes) to swim 2000 yards and his pulse rate (in beats per minute) after swimming for 23 sessions in the pool:

You made a scatterplot of these data in Exercise 14.13 (page 303). The leastsquares regression line is pulse rate = 479.9 − (9.695 × time)

The next day’s time is 34.30 minutes. Predict the professor’s pulse rate. In fact, his pulse rate was 152. How accurate is your prediction?

Exercise 14.13

The professor swims. Professor Moore swims 2000 yards regularly in a vain attempt to undo middle age. Here are his times (in minutes) and his pulse rate (in beats per minute) after swimming for 23 sessions in the pool:

(a) Make a scatterplot. (Which is the explanatory variable?)

(b) Is the association between these variables positive or negative? Explain why you expect the relationship to have this direction.

(c) Describe the form and strength of the relationship.
